The formula to calculate the concentration in nmol/L from ng/mL is:
\[ \text{Nmol/L} = \frac{\text{ng/mL} \times \text{MW}}{1000} \]
Where:
Ng/mL to nmol/L is a conversion between two units of measurement used in chemistry and biology. Ng/mL stands for nanograms per milliliter, which measures the mass of a substance in a given volume. Nmol/L stands for nanomoles per liter, which measures the amount of substance (in terms of number of molecules or atoms) in a given volume. The conversion between these two units depends on the molecular weight of the substance in question.
Let's assume the following values:
Step 1: Multiply the concentration by the molecular weight:
\[ 50 \times 180 = 9000 \]
Step 2: Divide the result by 1000:
\[ \frac{9000}{1000} = 9 \]
Therefore, the concentration is 9 nmol/L.
